Question

Solve the system by substitution.
 -4.5x - 2y = -12.5  
3.25x - y = -0.75

anonymous · Answer

Solve one of the equations for either x or y and then plug that into the other equation.

anonymous · Answer

Which one do you want to solve and for either x or y? Hi

( hint look for something easy like x or y with no value in front of it)

anonymous · Answer

X seems the easiest. times both sides by 2 to take out all the Ys?

|dw:1355431203860:dw| Make a x and y table.. that is the first step

phoenixfire · Answer

Rearrange the second equation so you have y=......
Show me what you get.

phoenixfire · Answer

$-4.5x - 2y = -12.5$ <- EQ (1)
$3.25x - y = -0.75$ <- EQ (2)

If you take (2) and rearrange for y.$$y=3.25x+0.75$$Now substitute this into (1) and solve for x$$-4.5x - 2(3.25x+0.75)=-12.5$$
Can you solve this equation?
